Darkness. The door into the neighboring room is not quite shut. A strip of light stretches through the crack in the door across the ceiling. People are walking about by lamplight. Something has happened. The strip moves faster and faster and the dark walls move further and further apart, into infinity. This room is London and there are thousands of doors. The lamps dart about and the strips dart across the ceiling. And perhaps it is all delirium...Something had happened. The black sky above London burst into fragments: white triangles, squares and lines - the silent geometric delirium of searchlights. The blinded elephant buses rushed somewhere headlong with their lights extinguished. The distinct patter along the asphalt of belated couples, like a feverish pulse, died away. Everywhere doors slammed and lights were put out. And the city lay deserted, hollow, geometric, swept clean by a sudden plague: silent domes, pyramids, circles, arches, towers, battlements.
